alacritty: window.opacity doesn't seem to work

I have set the opacity to 0.9, via window.opacity. But the opacity doesn’t seem to change. What’s the case?

Things I’ve tried/verified:

1. The indentation is correct. (2 spaces per tab)
2. I have only 1 instance of window.opcacity
3. My compositor (picom) is working, I’ve tried it with no configs, too
4. The opacity value is detected, verified by increasing the opacity to over 1, which causes the screen to go white
5. Tried upgrading and restarting the system, tried with different, kernels, still didn’t work

System

OS: Linux Version: alacritty 0.11.0 (8dbaa0bb) Linux/BSD: Xfce4, XmonadWM, picom
